An unexpected upside to a drought in Queensland, Australia: Researchers now have a better sense of what a fearsome sea creature of yore looked like. A cattle farmer stumbled across a fossil in his field that turned out to be the lower jaw of Kronosaurus Queenslandicus, which plied the local waters about 110 million years ago.

And not just any jaw—the 5-foot-long specimen is the most intact ever found of the Kronosaurus, known to have reached a body length of 36 feet, ABC Online reports.
